$k$-spaces and products of closed images of metric spaces

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Products of hyperbolic metric spaces

Products of hyperbolic metric spaces II

In [FS] we introduced a product construction for locally compact, complete , geodesic hyperbolic metric spaces. In the present paper we define the hyperbolic product for general Gromov-hyperbolic spaces. In the case of roughly geodesic spaces we also analyse the boundary at infinity.

Products of k-spaces, and questions

As is well-known, every product of a locally compact space with a k-space is a k-space. But, the product of a separable metric space with a k-space need not be a k-space. In this paper, we consider conditions for products to be k-spaces, and pose some related questions.

On Π-images of Metric Spaces

In this paper, we prove that sequence-covering, π-images of metric spaces and spaces with a σ-strong network consisting of fcs-covers are equivalent. We also investigate π-images of separable metric spaces.
